Specification of Letters Patent.

Patented May 28,1912.

Application filed September 12, 1911. Serial No. 648,825.

To all whom it mdy concern Be it known that I, ABRAHAM GROVE REA- MAN,of the village ofRingwood, in the county of York and Province ofOntario, Canada, blacksmith, have invented certain new and usefulImprovements in Vehicle- Wheels; and I hereby declare that the followingis a full, clear, and exact description of the same. 7

My present invention relates to that class of vehicle wheels in whichthe felly is yieldingly supported from the axle. In certain types ofthis class of wheel the felly is connected with the hub by yieldingspokes, made in two parts one of which slides within the other,suitable. springs being provided to i resiliently hold the partsintheirnormal position, and these spokes, owing to thelr separableconstruction, lack rigidity, bend circumferentially and laterally undervarying conditions of load and use, and permit of the wheel to buckle,and in some cases break.

'My present invention further relates to the axle whereby the wheel canhave limited radial movement relative to the axle when yielding to thecondition of the load, and, the surface over which the wheel istraveling, the object of my invention being to so arrange these elementsthat the wheel will have the same resiliency as when provided with apneumatic tire.

: For an understanding of the invention reference is to be had to thefollowing description and to the accompanying drawings in which Figure1, is a side elevation of a vehicle wheel, partly in section, showingthe relative position and construction of the parts. Fig. 2, is avertical section through the hub. Fig. 3, is a section on the line a-aFig. 2, and Fig. 4, is an elevation of one of the hub plates.

Like characters of reference refer to like parts throughout thespecification and drawm s.

In the construction of the wheel I connect the felly a and the hub 12 byrigid spokes 0, the felly and spokes beirw similar to those now used,the hub being hollow, and, larger than the ordinary hub to receive theparts relating to my invention, and the felly being provided with a tired which may be of metal or solid rubber, as the wheel does not dependupon the tire for its resiliency.

The hub 72 comprises two side plates 6', b, spaced apart, each having acentral bore 6 of relatively greater diameter than the boxing for theaxle f to permit of a limited movement of the hub without comingintocontact with the boxing or axle during the yielding movement ofthewheel. The inner faces of the side plates are provided with annularrings 9 g, the ring 9 being in:

tegral with thesideplate b, and the ring 9 being separate from, butbolted to, the side plate I), to hold the spokes in position, and theinner faces of the side plates 6 b are provided with circular flanges2', concentric with the rings 9 g, and, adjacent to the bore 6. Withinthe bore 6 is the boxing for the axle arm f, the boxing being ofrelatively smaller diameter than the bore 6 so that the wheel can yieldradially from its normal position independently of the boxing withoutthe edge of the bore coming into contact with the boxing.

Integral with the boxing j is a drum 7a having radial slots Z in itssides 70, and contained in the drum is are cushioning springs m. Thecushioning springs engage at their outer ends against movable bars 0transverse to the length of the cushioning springs m and slidableradially with respect to the center of the boxing, and at their innerends against similar sliding blocks 39. The bars 0 project beyond thesides of the drum k and are provided with rollers g engaging with theinternal surfaces of the annular rings 9 g. The sliding blocks 22 areprovided with projections 1 engaging with the peripheral surfaces of thecircular flanges z. The inner surfaces of the side plates 1) b areprovided with radial stops 8 extending inwardly from the rings 9 g toengage with the rollers g and cause the united revolution of the wheeland boxing. I have shown in Fig. 2, a boxing element provided with ninesets of cushioning springs, movable bars, rollers, and sliding blocks,but this number may be altered to meet different requirements underdifferent conditions of use and size of wheel.

When the load is on the wheel, the axle f forces the boxing j and drumis downward, compressing the lowermost set of springs m,

against its respective bar 0, the rollers of that bar resting forciblyon the annular surface of the rings 9 g. It also, through the engagementof the projections r with the circular flanges 2', causes the outwardmovement of the uppermost sliding blocksp, and the compression of theirrespective springs against the bars 0. This causes the lower most anduppermost springs to sustain the major part of the load on the wheel,the balance of the load being evenly distributed from the lowermostsprings upward, and from the uppermost springs downward un til the linesof force meet. In this way the entire load upon the wheel is distributedto all of the sets of springs, so that the hub, under normal use, willbe constantly concentricwith the boxing and axle, and under abnormalconditions of load and roadway it will be eccentric to the boxing. -Insuch cases however .the difference between the relative sizes of thebore and boxing compensates for the change in their relative positions.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is:

In a vehicle wheel, a hub having a central bore for the boxing, said hubcomprising two side plates, the inner faces of which are provided withannular flanges in juxtaposition to the bore, and other annular flangesnear their outer ends, a boxing of relatively smaller diameter than thebore of the hub, comprising a drum provided with radial slots, movableelements slidably contained in the outer ends of said slots and providedbeyond the sides of the drum with rollers engaging the annular flangesnear the outer ends of the side plates, and movable elements slidablycontained in the inner ends of the radial slots and engaging with theannular flanges of the side plates in juxtaposition to the bore, andsprings contained in the radial slots bearing against the movableelements.
